COLORIA's Global Projects: Concrete Board Real Photos from Europe to Saudi

Barcelona's "Haven of Quietude": A Boutique Hotel Wrapped in Honest Materials

Nestled between Barcelona's Gothic Quarter and the bustling La Rambla, Hotel Serenity is a study in contrasts. Its exterior, a mix of weathered brick and modern minimalism, hints at the calm within. Step through the oak doors, and you're greeted by a lobby that feels less like a hotel and more like a friend's thoughtfully curated home.

The star here? Fair-faced concrete . Not the cold, industrial stuff you might imagine, but a warm, tactile version that lines the walls from floor to ceiling. Run your hand along it, and you'll feel the subtle texture of the formwork—like the memory of human hands shaping something lasting. "We wanted the space to feel grounded," says Elena Martí, the hotel's interior designer. "Fair-faced concrete does that. It's unapologetically real, no pretense. Pairing it with soft linen sofas and warm wood accents keeps it from feeling stark."

But the concrete isn't alone. Above the reception desk, a sweeping backsplash of travertine (starry blue) steals the show. The stone's creamy base is threaded with veins of deep, midnight blue—like someone spilled a constellation across its surface. "We chose starry blue because Barcelona's sky at dusk is exactly this color," Elena explains. "Guests often pause here, just staring at it. It's like bringing a piece of the Mediterranean night indoors."

Upstairs, the guest rooms continue the theme. Bathrooms feature polished concrete floors that warm underfoot, while headboards are clad in thin slices of boulder slab (vintage gold) . The vintage gold finish, with its soft metallic sheen, catches the morning light filtering through linen curtains, turning ordinary mornings into something a little magical. "A guest once told me the room felt 'like waking up inside a seashell—quiet, safe, and full of light,'" Elena smiles. "That's the power of these materials. They don't shout; they whisper."

Riyadh's Cultural Beacon: Where Heritage Meets Innovation

In Riyadh's King Abdullah Financial District, a new landmark rises: the Al-Majd Cultural Center. Designed to honor Saudi Arabia's rich history while embracing modernity, its facade is a dialogue between past and present. The star here? boulder slab (vintage gold) panels, arranged in a pattern that echoes traditional Najdi latticework. "The desert sun hits those panels just right at noon," says lead architect Omar Al-Saud. "They glow like liquid gold. It's not just a building—it's a celebration of our landscape."

Inside, the center's grand hall is a masterclass in material harmony. The walls are lined with rammed earth board (matcha green) , a nod to the region's ancient mud-brick architecture. But this isn't your grandmother's mud brick. COLORIA's rammed earth boards are reinforced for durability, with a smooth, velvety texture that feels cool to the touch—perfect for Riyadh's heat. "We wanted to connect visitors to our roots," Omar explains, "but in a way that feels fresh. The matcha green hue is unexpected, but it works. It's like a desert oasis, bringing a pop of life to the space."

Downstairs, the exhibition galleries feature travertine (starry blue) flooring, the same stone from the Barcelona hotel but used here to different effect. Under gallery lighting, the blue veins seem to shift and flow, guiding visitors through displays of Saudi art and history. "It's subtle wayfinding," Omar notes. "The stone itself tells you where to go." Near the entrance, a water feature cascades over a wall of foamed aluminium alloy board (vintage silver) , its metallic surface catching the water and turning it into a glittering curtain. "Aluminium is lightweight but strong—ideal for a structure that needs to stand tall in the desert wind," Omar adds. "And that vintage silver? It mirrors the sky, making the building feel like it's reaching up to touch the clouds."

Berlin's "Green Workplace": Where Sustainability Feels Like Second Nature

Berlin's tech scene is all about innovation, and the new headquarters of GreenWave Tech fits right in. But instead of the usual glass-and-steel monotony, the building wraps itself in foamed aluminium alloy board (vintage silver) , a material that's as eco-friendly as it is eye-catching. "We wanted a facade that reflects our commitment to sustainability," says Jan Richter, GreenWave's CEO. "Foamed aluminium is 100% recyclable, and its lightweight nature cut down on construction emissions. Plus, that vintage silver finish? It shimmers in the Berlin sun, making the building look like it's alive."

Inside, the open-plan offices are a lesson in balancing productivity and calm. Columns are wrapped in fair-faced concrete , their rough texture a contrast to the sleek aluminium desks. "Concrete absorbs sound, which is a game-changer in a busy office," Jan laughs. "No more shouting over cubicles!" Breakout areas take the "green" theme further, with walls clad in rammed earth board (matcha green) . The soft, earthy tone pairs with potted olive trees and natural wool rugs, creating spots where employees can recharge. "We've noticed people stay longer here now," Jan says. "They don't just grab coffee and run—they linger, chat, collaborate. The space invites connection."

Even the rooftop terrace gets the COLORIA treatment. Planters are made from boulder slab (vintage gold) , their warm hue complementing the city skyline at sunset. "It's become our favorite spot for team meetings," Jan admits. "There's something about that gold stone against Berlin's gray buildings—it feels like we're sitting on top of the world, but in the best, most grounded way."
